一.调用第三方接口的方法
function https_request($url,$type=’get’,$res=’json’,$data = ”){
//1.初始化curl
$curl = curl_init();
//2.设置curl的参数
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST,2);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
if ($type == “post”){
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
}
//3.采集
$output = curl_exec($curl);
//4.关闭
curl_close($curl);
if ($res == ‘json’) {
return json_decode($output,true);
}
}
二.获取用户的openid
function getBaseInfo(){
$appid = “我的ID”;
$redirect_uri = urlencode(“http://www.XXXXXXX.com/XXXXX/XXXXXX.php/Index/getUserOpenId”);
$url = “https://open.weixin.qq.com/connect/oauth2/authorize?appid=”.$appid.”&redirect_uri=”.$redirect_uri.”&response_type=code&scope=snsapi_base&state=614#wechat_redirect”;
header(‘location:’.$url);
}
三.获取用户的access_token
function getUserOpenId(){
$appid = “我的ID”;
$appsecret = “我的secret”;
$code=$_GET[‘code’];
//2.获取到网页授权的access_token
$url = “https://api.weixin.qq.com/sns/oauth2/access_token?appid=”.$appid.”&secret=”.$appsecret.”&code=”.$code.”&grant_type=authorization_cod”;
//3.拉取用户的opendi
$res = $this->https_request($url);
var_dump($code);
var_dump(”
“);
var_dump($url);
var_dump(”
“);
dump($res);
}
获取不到网页授权接口的code,打印三个值结果如下:
NULL string(5) ”
” string(149) “https://api.weixin.qq.com/sns/oauth2/access_token?appid=我的ID &secret=我的secret&code=&grant_type=authorization_cod” string(5) ”
” array(2) { [“errcode”]=> int(41008) [“errmsg”]=> string(47) “missing code, hints: [ req_id: 3MmDtA0251s113 ]” }
问题已经找到，相信很多人和我一样没发现问题在哪。如下所示，应该是code。从官网拷贝的链接，不知道咋弄的，少了一个字母…然而这里不需要拼装参数，所以一直没发现…
